Problem Behaviors and Interventions

Prob Bx #1- ‘Does Supplementary Reinforcement of Stereotypy Facilitate Extinction?’ by Dozier, Iwata, Wilson, Thomasson-Sassi, & Roscoe (2013)Abstract- …Studies suggest that delivery of supplemental (social) reinforcement for stereotypy might facilitate its subsequent extinction. We examined this possibility with 9 subjects who engaged in stereotypy by including methodological refinements to ensure that (a) subjects’ stereotypy was maintained in the absence of social consequences, (b) supplementary reinforcers were highly preferred and were shown to be reinforcers for some behavior, and (c) subjects were exposed to lengthy reinforcement and extinction conditions. In spite of these modifications, only 4 subjects’ stereotypy increased when supplementary reinforcement was delivered contingent on stereotypy, and no subject’s stereotypy decreased below initial baseline levels when social reinforcement was subsequently withheld.[sic]
